@Override
public void apply() {
    // Compute reference position
    Vector2 referencePos = new Vector2(reference.getWidth() * referenceAnchor.hPercent,
            reference.getHeight() * referenceAnchor.vPercent);

    Vector2 stagePos = reference.localToStageCoordinates(referencePos);

    // Apply space
    stagePos.add(hSpace, vSpace);/*from w ww . ja va  2 s  .  c  o m*/

    // Position target (use target parent because setPosition() works in parent coordinates)
    Actor targetParent = target.getParent();
    if (targetParent == null) {
        return;
    }
    Vector2 targetPos = targetParent.stageToLocalCoordinates(stagePos);

    // Apply target offset (If right-aligned, hPercent is 100% => -width * scale.
    // If centered, hPercent is 50% => -width * scale / 2)
    targetPos.add(-target.getWidth() * target.getScaleX() * targetAnchor.hPercent,
            -target.getHeight() * target.getScaleY() * targetAnchor.vPercent);

    //noinspection SuspiciousNameCombination
    target.setPosition(MathUtils.floor(targetPos.x), MathUtils.floor(targetPos.y));
